Research on a Nonlinear Fuzzy Comprehensive Assessment Method for Oil & Gas Pipeline Failure Based on Fault Tree Analysis

Abstract:

The combination method of fault tree analysis and nonlinear fuzzy comprehensive assessment method was proposed to make research of oil & gas pipeline failure .The common factors influencing oil & gas pipeline failure could be determined with fault tree analysis .However , the practical operated oil & gas pipeline often have some individual factors and fuzzy ones .Nonlinear fuzzy comprehensive assessment method could evaluate objectively based on evaluated factors sets and weight sets provided by fault tree analysis .The new model steps were listed by taking the example of oil & gas pipeline failure .The result indicates that the method is more reasonable and easier for engineering application , and the evaluation result is more with the objective reality.
